The WR322GR-EC-LoRaWAN is a programmable cellular or Ethernet gateway for LoRaWAN communication. The Semtech S1301 supports the LoRAWAN protocol for long-range wireless connection to multiple LoRaWAN nodes. The WR322GR-EC-LTE-LoRaWAN gateway converts LoRaWAN™ data to MQTT and transmits to the cloud through the LTE network. The gateway comes with two software-selectable RS-232/422/485 Modbus full-signal serial ports and two 10/100/1000 Mbps Ethernet ports. The built-in Node-RED flow-based programming in the gateway provides a reliable and secure gateway for data acquisition and processing at field sites as well as a user-friendly communication platform for many other large-scale deployments. Combining with the new LoRaWAN controller LR140, Cloud platform ThingsMaster, and various environmental sensors, WoMaster presents complete IoT Environment Monitoring applications.
